NJM2113M

SIP8 is the NRND product as of February,2023 NJM2113 LOW VOLTAGE AUDIO POWER AMPLIFIER ■ GENERAL DESCRIPTION The NJM2113 is an audio power amplifier designed for telephone application, such as in speakerphones. Coupling capacitors to the speaker are not required,as it has differential speaker outputs. The closed loop gain is set with two external resistors. A CD pin permit powering down with muting the input signal. ■ PACKAGE OUTLINE NJM2113D ( DIP8 ) ■ FEATURES ● Wide Operating Voltage ( 2~16V ) ● Low Operating Current ( 2.7mA Typ. ) ● CD Input to Power Down the IC with Mute NJM2113E ● Low Power-Down Operating Current ( 72μA Typ. ) + ( SOP8 ) ● Output Power Exceeds 250mW ( V =6V,RL=32Ω ) ● Gain Adjustable (GVD=0~43dB,Voice Band ) ● Package Outline DMP8, DIP8, SOP8 JEDEC 150mil SIP8, SSOP8, VSP8 ● Bipolar Technology ■ RECOMMENDED OPERATING CONDITIONS ● Load Impedance RL 8~200Ω ● Differential Gain GVD 0~43dB ( 5kHz bandwidth ) ● Input Voltage at CD VCD 0~V+ Vdc NJM2113R ( VSP8 ) NJM2113M ( DMP8 ) NJM2113V ( SSOP8 ) t c du ro P D N NRNJM2113L ( SIP8 ) ■ PIN CONFIGURATION PIN FUNCTION 1.
